20.2. 在 Satellite 服务器中取消注册

流程

1. 从 Satellite 服务器 中删除主机。

2. 取消系统注册：

   # subscription-manager unregister

   Copy to Clipboard

3. 将 /etc/rhsm/rhsm.conf 配置文件恢复到其默认值：

   # cd /etc/rhsm/
   # mv rhsm.conf.bak rhsm.conf

   Copy to Clipboard
   注意

   只有在之前备份了文件的原始内容时，才能恢复此文件。否则，您必须手动从非修改的 RHEL 机器恢复该文件。

4. 验证 /etc/rhsm/rhsm.conf 文件是否已恢复为默认值：

   # subscription-manager config --list
   [server]
      hostname = [subscription.rhsm.redhat.com]
      insecure = [0]
      no_proxy = []
      port = [443]
      prefix = [/subscription]
      proxy_hostname = []
      proxy_password = []
      proxy_port = []
      proxy_scheme = [http]
      proxy_user = []
      server_timeout = [180]
      ssl_verify_depth = [3]
   
   [rhsm]
      auto_enable_yum_plugins = [1]
      baseurl = [https://cdn.redhat.com]
      ca_cert_dir = [/etc/rhsm/ca/]
      consumercertdir = [/etc/pki/consumer]

      pluginconfdir = [/etc/rhsm/pluginconf.d]
      plugindir = [/usr/share/rhsm-plugins]
      productcertdir = [/etc/pki/product]
      repo_ca_cert = /etc/rhsm/ca/redhat-uep.pem
      repomd_gpg_url = []
      report_package_profile = [1]
   
   [rhsmcertd]
      auto_registration = [0]
      auto_registration_interval = [60]
      autoattachinterval = [1440]
      certcheckinterval = [240]
      disable = [0]
      splay = [1]
   
   [logging]
      default_log_level = [INFO]
   
   [] - Default value in use
